Answer:
To compare an object or an idea, you list the similarities between one thing and another. You can compare the physical characteristics of something, or its personality, plotline, outcome, or your opinion of it.
Contrasting something means finding the differences of two or more things. When contrasting, you think about what differentiates one thing from another.
By both comparing and contrasting, you can find patterns between things, choose one over another, and understand deeper the meanings of them.
